Buzzards Race Report

[Fb.Paul]

This is what happens when you lose your rear sprocket at 60 mph.

My assumption is that either the sprocket warped from heat, or was bent from hitting a rock (probably more likely), which then caused it to stress the bolts too hard and they started falling out 1 by 1. Eventually the hub couldn't take it so it failed, which sent the chain flying forward, mangled in the countershaft.
